The relentless human desire to know – to satisfy curiosity at all costs – can be more of a curse than a blessing, according to scientists. Whether it’s surreptitiously checking your partner’s phone for signs of infidelity, avidly reading celebrity gossip mags, or hunting people down on social media, too much curiosity can be like opening Pandora’s Box: the urge to do it can outweigh any benefits you might get from knowing, and it can seriously affect your happiness and wellbeing.

The scientists carried out four experiments that exposed people to electric shocks with no apparent benefits, to prove a point that people were driven by “humans’ deep-seated desire to resolve uncertainty, regardless of the harm it may bring”. One experiment involved clicking colour-coded pens, some of which had electric shocks and some didn’t. Where there was uncertainty (not clear which colour pens had batteries) people clicked more of the pens.

The researchers said: “The study suggests that humans possess an inherent desire, independent of consequentialist considerations, to resolve uncertainty; when facing something uncertain and feeling curious, they will act to resolve the uncertainty even if they expect negative consequences. Just as curiosity drove Pandora to open the box despite being warned of its pernicious contents, curiosity can lure humans—like you and me—to seek information with predictably ominous consequences.”

Something to bear in mind before you start secretly stalking your ex on social media. Sometimes, for your own happiness, it may be better just not to know.
